DUMIING RAILWAY-CAB.

Specicetion of Letters Patent.

Patent-ed Apr. 19, 1910.

Application tiled October 28, 1909. Serial No. 525,036.

To all whom it may concern:

Be it known that I, Join: .Eiiiosoin a citizen of the United States, residing at C.lii cago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Dumping Railway-Cars, of which the following is a specificetion.

My invention relates to dumping railway cars more generally known as gondola freight cars.

The object of iny invention 1s .to provide a car of the character mentioned in which the dumping doors embodied therein may be readily and quicklyunlocked and svvung to openin or dumping position which inay iis easi y and expeditiouslyr return to closing position. l

Another object is the provision of a dumping car which will be so designed that the load carried thereby, when dumped, will be deposited outside of. or laterally beyond the truck railsand hence in a position in which the progress of the car wheels will not be im peded thereby.

A further object is to provide a car which throughout will be of a strong, durable, and economical construction.

Other-objects will appear hereinafter. Y

W'ith these objects in view my invention consists in a railway cer characterized as above mentioned and in certain details of construction and arrangement of parts all as will be hereinafter fully described und more particularly pointed out in the uppended claims.

My invention will be more rendlly underv stood by reference to the accompanying drawings forming a. part of this specificetion, and in which.

Figure 1 is a side elevation of I ny duinping car in its preferred form, Fig. 2 1s a top plan View thereof, Fig. 3 is an enlarged bottom plan showing substantially one-half of the cur, Fig. 4 is an end elevation thereof, Fig. 5 is a vertical transverse section token on substantially the line :iz-.r o f Fig. 3, Fig. (i is e vertical transverse section taken on line :1j-'y of Figs. 1 or 3, Fig. 7 1s mi. cnlurged sectional detail taken on substantially the line z-zvof Fig. l, Fig. 8 is n fragments-ry detail illust-rating the operation of the dumping door operating and locking mechanisms, and Fig. 9 is :i slightly enlarged detail pers ective of one of the door-hinge shields ein odied in the construction, and

-charge opening.

lIfilg. 10 un enlarged detail of the locking Referring now to the drawings 1 indicates the sheet metal body of the car mounted in the usual manner u on suitable wheel trucks Included in sai body are the vertically disposed preferably integrally formed side und end Walls 3 3 respectively, und the transversely arcuate or substantially semicylindrical bottom 4, said end Walls only being extended und secured directly to said bott-om. Centrali positioned :ind longitudinnlly extending eneath the bottoni 4 area pair of supporting channel center sills 5 reinforced et intervals by transversely extending connecting plates 6. Provided at intervals also beiieetli the bottom 4 are supporting segmental plates T the vertical inner edges of which are secured to the outer vertical sides of the sills 5. the upper curved edges thereof resting iii engagement with the under surface of tho bottoni 4. Having their central portions engaging straps 8 secured at intervals to and depending from thc sills 5 und their extremities secured to the longitudinal edges of the bottom 4 are rein-- forcing trusses 9 preferably formed of T- iron, the purpose of which is to form additional supports for the center of the oonstruction.

Tra-nsversely extending in the body is a plurality of preferably equally spliced re nforcing ribs or partitions 10 the outer or contacting edges of which are flanged to facilitate o rigid securing thereof to the bottom 4 :ind side walls 3. Extending benczith successive partitions 10. the saine being secured thereto and to the bottom fl are centrally positioned longitudinally extending angular hoods 11 the purpose of which is to divide mid deflect the descending or dumping load to directit toward the dis- Ti'uiisversely extending upon and riveted to the end wells 3 intel'- mcdiate the upper :ind lower oxtreniitics thereof. ure T-irons 1:2 und upon the side walls 3 adjacent tho lower odge thereof angle irons 13, the purpose of which in either ruse boing to add to the strength und durability m5 of the construction,

Secured us by rivets 14 to the inner surface of the sido walls 3 adjacent the lower edges thi-roof uro u serios of ulning pluies l5 cncli of which extends lit-tween udjucont.

partitions l0. Having its upper edge rig- 110 idly secuxed close to the up er edge of each of the plates la, the same enig preferably formed integrally therewith, is en inwardly obliqucly disposed plate 16, an. lmportant pur ose of which will be hereinafter de scrilied. Spacing seid plates 15 and 16, the same de ending therefrom and being preferrbly ormed integrally therewith, are a series of hinge lugs 17 to which are hlngedly secured a series of depending dumping doors 18 which, when in innermostor closed osition entirely close the bottom of the car dy. Each of said doors is comprised of a substantially rectangular metallic plate 19 reinforced at its lateral and upl'er edges by angle bars 20 and interrne late the former by a series of cross bars 21, the upper ends of said lateral and intermediate cross bars being extended for connection with the hinge lugs 17. The lower edge 22 of each of the plates 19 is flanged or bent outwardly, said ed e being adapted when said doors are in clgosed position, to rest in engagement with the upper outer edge of the bottom 4.

lVith the construction as described, it will be observed that the hinge connections of the dumping,r doors with the body side walls are exteriorly guarded by the lower edge of the latter and internally by the obliquely disposed plate 16, hence the possibility of injury thereto so as to render the same inoperative is reduced to a minimum.

Mounted beneath the bottom 4 close to the lateral edges of the latter in bearings formed in the plates 7, are longitudinally extending shafts 23, preferably four in number, two being provided upon either side, each of which extends from the center of the body to one extremity thereof. Having their inner extremities secured rigidly to the shafts 23, are spaced projecting arms 24. Having their inner bifurcated extremities pivoted to the outer extremities of the arms 24 and their outer bifurcated extremities pivoted to lugs 25 secured to and downwardly projecting from the lower edges of the doors 18 adjacent the extremities thereof, are curved links 26. Said parts are so arranged in proportion that, when the shafts 23 are in one position, or as clearly shown in F igs. (i and 7, the doors 18 will be held in closed position, and when said shafts ars rotated to another position, or as shown in Fig. 8, said doors will be swung to the opened stion. Further said parts are so proportioned that when in closing osition the arms will be slightly over deadpcentcr, hence the construction will he self locking, however, as a sate guard affainst accident, other locking means, as will1 be hereinafter described, have been provided. In order to eilect the actuating rotation of tlu.l shafts 23 each is provided at its extcriorly rojecting outer extremity with a spr e et 27. Traveling over each of the latter and a similar sprocket 28 rotatably mounted in the hotly und wall and u bracket 9.9 secured to the latter, the sume passing through the end sill of the car body is a sprocket chain 30.

By means of handles 31 fixed to the sprocket- 28, the rotation thereof hence of the shafts 23, and consequently the operation of the doors 18 may evidently be effected. Pivoted arms 32 arranged adjacent the handles 31 are adapted to be rocked to engage and to hold. the same in closing osition by preventing reverse movement thereof.

Keyed to each of the shafts 23 at points thereon substantially opposite the centers of the doors 18 are eccentrics 33 mounted upon each of which is an eccentric strap 32h Rockingly mounted between brackets 35 secured to and depending from the bottom 4 are bell crank levers 36 the inner ends of which are connected to the straps 34. The forward ends 37 of said levers are hooked in form, as clearly shown in Fi s. 5 and 8, said construction being so a justed, that, when the shafts 23 are in a sition in which the doors 18 are closed, sai forward hooked ends 3T of said levers will engage the lower edges of said doors, as clearly shown in Fig. 5 and in dotted lines in Fig. 8, to hold said doors in such position; but upon the rocking of said shafts from such position, said levers will be rocked, as shown in full lines in Fig. 8, to dlsengage said doors permitting of the out ward swinging or opening thereof. Hence it will be observed that the unlocking and openlng or the closing and locking of the dumping doors, in the construction thus far described, may be simultaneously effected by the rotation or actuation of the handles 31. As a still further safeguard in locking said doors in closed position, I provide each of the latter with a sliding bolt 38 mounted upon u plate 39 rigidly secured to the front surface of the former. The flanged lower edge 22 of each door is provided with a perforation 40l arranged in axial alinement with and adapted to receive the bolt 38, and the lateral edges of the bottom 4 with similar perforations 41 so arranged that the ierforations 40 will register therewith w ien the doors are in closed position. B f means of handles 42 Eovided upon each olt 38, the

latter may readil slid to locking or unlockin positwn. y means of notches 43 form 1n a flange project-ing from one of the edges of cach of the plates 39, for the reception of the handles 42, the latter muy he readily held in raised or lowered that is lut-king or unlocking position, hence with such construction when the doors are in' closed position, the bolts 3S may be -dro )pcd into the perforations l0 and l1 to positivi-ly lock the same in such position, and upon desiring;r to o n said doors said bolts may he raised to dlsenga e said perforation and hence to lelease sai doors.

By the provision of a eur of the construe tion described one of the. highest pos-:able ef* liciency .regarding both the strength, praeticiibilit-y and also one of a comparatively lowcost to build, will be provided.

While I have shown what l deem to the preferable form of my car, I do not wish to be limited thereto as there might be many changes in the details of construction and arrangement of part-s without departing from the spirit of the inventlim comprehendcd within the scope of the appended claims.
